MIT-ER-BOX.

Specification of Letters Patent.

Patented Feb. it, Milo.

AppIication filed January 28, 1908. Serial No. 412,956.

To all whom it may concern:

Be it known that I, WILLIAM Forum, a citizen of the United States ofAmerica, and residing at New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements inMiter-Boxes, of which the following is a specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

The object of this invention is to provide a miter box for the use ofcarpenters and others by means of which an ordinary saw may be employedto cut wood or other materials at various angles; a further object beingto provide a miter box which permits of the material to be out beingplaced therein from above instead of from the end as in devices of thisclass as heretofore constructed, and by means of which the saw, when notin use, may be left in the miter box and be entirely out of the way; afurther object being to provide a miter box which may be set to outmaterial at any predetermined an gle on either side of a line at rightangles to the miter box without resetting, and a still further objectbeing to provide a device of this class which is simple and accurate inconstruction and operation, and which may be readily taken apart whennot in use and as readily re-assembled for use.

My invention is fully described in the following specification of whichthe accompanying drawings form a part, in which the separate partsthereof are indicated by suitable reference characters in each of theviews, and in which Figure 1 is a plan view of my invention ready foruse and arranged for a square cut. Fig. 2, a bottom plan view thereof.Fig. 3, a horizontal section thereof taken on the line 83 of Fig. 4, theparts being arranged at an angle of 45. Fig. 4, a ver- Fig. 5, a partialsection, somewhat enlarged, on the line 55 of Fig. 1. Fig. 6, anenlarged partial section on the line 66 of Fig. 3. Fig. 7 a verticalsection on the line 77 of Fig. 4, and Fig. 8, a partial section on theline 88 of Fig. 4.

In the drawings forming part of this specification I have shown a baseor support a which as shown in Fig. 4, is composed of two horizontalmembers a and a connected by means of vertical end members a and at theback of the member a I have provided two longitudinally arranged membersa which extend above the member a as indicated in dotted lines in Fig.4.

Mounted on a member a and above the same is a plate 6 which is securedto a tubular member to which is also secured a plate 6 beneath themember a and the plates 5 and b are connected together by means of abolt and thumb screw 6* which passes through the member a of the supporta.

Resting against the bottom of the member a is a plate 0 which is inpermanent connection with the plate 6 by means of a pin 0 and passingthrough the plate 19 are two adjusting screws 0 and 0 which bear againstthe plate 0 as clearly indicated in Fig. 4.

Rotatably mounted in the tubular member 5 is a vertically arranged tubed to which is secured a horizontally arranged tube d which isrectangular in cross section, and slidably mounted in the rectangulartube 6Z2 is a similarly shapedtube d which is adapted to be adjustedtherein and held by means of a spring catch or other device 6Z as shownin Fig. 3.

Mounted in the vertical tube d are two blocks preferably composed ofwood 6 and e which are held in the tube (5 by means of bolts and thumbscrews 6 operating in bayonet joints e", and it can be readily seen thatby this construction the blocks 6 and 6 can be readily removed and asshown in Fig. 7, these blocks are held together at their tops by meansof a screw 0 and said blocks are so formed as to leave a vertical slot 6therebetween which registers with a similar slot (Z in the tube d andthrough which a saw indicated in dotted lines at cl is adapted to bepassed.

By reference to Fig. 7 it will be seen that the blocks 6 and e are eachprovided with a slanting saw cut thereby forming spring tongue members 6which are held together by means of oppositely arranged screws e theslots in the heads of which register with openings 6 in the tube (Z, andby means of this construction it will be seen that when the blocks 6 ande are worn away by the manipulation of a saw therebetween the rotationof the screws 0 through the openings 6 will regulate the size of theslot 6 and thereby keep the saw in vertical position and away from theedges of the slot (Z at all times.

Secured to the outer end of the adjustable tube (Z is a verticallyarranged tube f which is slotted vertically as shown at f similarly tothe tube (Z and mounted in the tube 7 are blocks f which are similar tothe blocks 6 and 6 previously described with the exception that they arenot united at their tops thereby permitting the slot 7 which registerswith the slot f in the tube 7 to extend the full length of the blocks fand this permits the insertion of the saw (Z between the said blocks andthe position of the saw (Z is determined with reference to the supporta, by the position of the swinging arm or tube d Secured to the bottomof the vertical tube d are three rollers g which are arranged in linewith each other cent-rally of the tube at and is clearly shown in Fig.8. The rollers 9 pass between two spring plates 9 which are looselymounted in the bottom of the tubular member 6 and by means of thisconstruction it will be seen that the tube at and swinging arm mountedtherein are forced outwardly from the right angle position in eitherdirection by means of the springs 9 when the rollers g are slightly offthe center and the tendency thereof is always to force the arm (Z into aposition in line with the support a.

By reference to Fig. 3, it will be seen that the plate 6 is slottedcentrally and longitudinally thereof as shown at 72 and the said plateis also provided with a supplemented slot h at one side thereof, and inwhich are adjustably mounted a plurality of screws 72, which areprovided with tapered heads as clearly shown in Fig. 6, and the plate I)is also provided with a guide it upon which a scale is adapted to bearranged and with which a slide if operating in the slot h is adapted tooperate, and the slide it is adapted to be adjusted in any position bymeans of a thumb screw or similar device h at any point on the plate Z).

Rotatably secured at 2' to the plate or slide 71, is a plate 2' which isprovided with openings i and 2' and the taper-headed bolts or screws 72,are adapted to enter the opening i while a similar taper-headed bolt orscrew it secured in the slide it is adapted to enter the opening 2' andthis serves as a supple mental adjusting device for the slide it andsaves time in the adjusting thereof as well as obviating the necessityfor the close attention required when setting to the scale arranged onthe guide 72,, and as the taperheaded bolts 7L may be adjusted in theslot k and secured therein a plurality of fixed positions of the slide72, are thereby produced. v

Rotatably mounted on the tubular member 6 and on the plate Z) are twoarms is and k V which are provided with supports 70 at their outer endsthrough which pass set screws and the arms is and 70 are connected withthe sllde h by means of llnk members 76 and 1t will be seen that themovement of the slide h operates the arms Z: and la correspondingly,and, as clearly shown in Fig. 2-3, the positions of the arms 70 and 70determine the limit of movement of the swinging arm d and this positionof the arm (Z on either side of the square position is adjustable bymeans of the set screws .2 and it will be seen that when it is desiredto cut material at a certain angle at either side of the square positionall that is necessary is to manually move the swinging arm (Z over thecenter, and the said arm is then forced into and held in the desiredposition by means of the springs and rollers g as previously described.

In practice I prefer to make the blocks 6 and a about 2 t inches inlength whereas the blocks f are preferably much shorter, and the reasonfor joining the blocks 6 and c at their tops is that they may serve as aholding device for the saw d when not in use after the same has beenforcibly raised into its uppermost position and the material to be outcan then be placed into the miter box from above instead of from the endas in miter boxes now constructed, and it will be seen that the swingingarm (Z may be longitudinally adjusted and may also be adjusted at anyangle to the support a which may be desired, and by means of theconstruction shown and described my apparatus may be entirely takenapart in a few moments in order to store the same in a tool chest andmay be as readily re-assembled when desired, and various changes in andmodifications of the construction herein shown and described may be madewithin the scope of this invention without departing from the spiritthereof or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A miter box, comprising in combination asupport for the work, a laterally swinging saw guide and meanscomprising springs for retaining the guide at right angles to the workwhen so placed but tending when the saw guide is displaced therefrom tourge it farther in the same direction.

2. A miter box comprising the combination of a support for the work, alaterallyswinging saw guide carried thereby, devices adjustableindependently of such guide for limiting the lateral swing of said guideto determine the angle cut and means tending to throw such guide ineither direction from a position at right angles to the work toward suchlimiting devices.

3. A miter box comprising the combination of a support for the work, alaterally swinging saw guide carried thereby, laterally swinging arms,independent of said guide, for limiting the swing thereof to determinethe angle cut and adjusting devices on said arms to exactly gage thesaid angle.

4. A miter box comprisingthe combination of a support for the work, alaterally swinging saw guide carried thereby, laterally swinging arms,independent of said guide, for limiting the swing of said guide todetermine the angle cut, means for locking said arms at any angle andmeans comprising springs for forcing said guide against either one ofsaid arms.

5. A miter box, comprising a support for the work, a laterally swingingsaw guide carried thereby and saw receiving uprights carried by said sawguide, said uprights being slotted. and said slots being tapered towardtheir tops, thereby serving to hold the saw in a raised position.

6. A miter box, comprising a support for the work, a tube vertically androtatably mounted therein, a swinging saw guide longitudinallyadjustable in said tube, devices adjustable independently of said sawguide for limiting the lateral swing thereof and means comprisingsprings tending to throw said saw guide either direction from a posi*tion at right angles to the work toward said limiting devices.

7. A miter box, comprising a support for the work, a laterally swingingsaw guide carried thereby, a laterally swinging arm on each side of saidguide, a plate movable in said support, links connecting said arms withsaid plate, means for locking said plate in desired positions to adjustsaid arms and limit the swing of said guide and thereby determine theangle cut, and means comprising springs tending to throw said guideeither direction from a position at right angles to the work toward saidlimiting arms.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 27th day of January,1908.
